In Valenciennes, former coalfield industry and motorway traffic is the primary local source affecting air quality, near the Scarpe, and North Sea winds sweep across the open plains, which helps maintain reasonable air quality across the year. Winter can see particulate build-up during still, cold spells, while summer generally benefits from stronger regional winds, aside from occasional cross-border ozone episodes.

In Valenciennes, the combination of former coalfield industry and motorway traffic and heavy birch and oak pollen in spring is what most affects sensitive groups; North Sea winds sweep across the open plains, so poor conditions rarely last more than a couple of days. The presence of Picardy and Artois arable plains in the area adds another layer to the local pattern.
Are air quality levels in Valenciennes based on measurements or forecasts?
It is forecasts derived by downscaling forecasts provided by EU’s Copernicus Atmosphere Monitoring Service (CAMS) by taking into account local conditions such as traffic patterns. CAMS bases its forecast on satellite measurements of particles and chemical compounds in the atmosphere. Airmine’s services were developed with support from the European Space Agency (ESA)’s Business Applications and Space Solutions (BASS) team.
